Abstract
The invention discloses an LED display device, comprising a sectional material, a surface cover, a circuit board and a membrane, wherein the circuit board is installed on the back surface of the surface cover, the membrane is patched on the front surface of the surface cover; an LED lamp is patched on the circuit board and a slot for installing the LED lamp is opened on the surface cover; the installation clamping plates are installed on two symmetrical sides of the back surface of the surface cover; notches are opened on two symmetrical ends on the circuit board; the surface cover is clamped on the sectional material; the circuit board installed on the back surface of the surface cover is suspended in the concaved cavity of the sectional material. The circuit board is not contacted with the sectional material so that the service life of the circuit board is effectively guaranteed. The invention has the advantages of easy assembly, good waterproof performance and excellent display effect and is widely used on the display screen for the outdoor advertisement.
Description
Technical field
The present invention relates to a kind of LED display device, specifically a kind of LED display device that is mainly used in the outdoor advertising demonstration.
Background technology
Outdoor advertising shows the contents such as literal, picture, animation and video of variation with LED display through versicolor LED lamp, and content can be changed at any time.At present outdoor two sides is turned over or three faces turn over LED display, and is good to the display effect of the numeral that changes, literal, graph image, have video wall, LCDs, projector incomparable advantage.Turn on existing two sides or three faces assemble with section bar after turning over cover and the circuit board fixed installation in the LED display mutually; After this cover and the section bar assembling; Need to carry out encapsulating at cover one side earlier, carry out encapsulating at the cover opposite side again after the completion, realize the fully fixing of cover and section bar; Mount overlay film on the cover again, the overlay film generally area than cover is big.It is tabular that the cover of this version generally is, and one side of its dress LED lamp need be provided with protruding block, is convenient to the locking of screw, causes this face of cover uneven, be unfavorable for installing, and operating procedure is complicated.In addition, the bottom surface of circuit board directly contacts with the upper surface of section bar, is prone to circuit board is caused damage.
Summary of the invention
The technical matters that the present invention will solve provides a kind of long service life, LED display device that manufacturing cost is lower.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
A kind of LED display device comprises section bar, cover, circuit board and overlay film, and circuit board is loaded on the cover back side; Overlay film is mounted on the cover front, is pasted with the LED lamp on the circuit board, offers the groove position that the LED lamp is installed on the cover; Symmetrical dual-side is provided with the installation clamp on the back side of said cover; Two ends symmetrical on the circuit board offer breach, and cover is installed on the section bar, and the circuit board that is loaded on the cover back side is suspended in the cavity of section bar.
The said cover back side is provided with and is positioned at the inboard baffle plate of clamp.
Offer the counterbore position on the said overlay film, and it is consistent to be used for the shape and the quantity of groove position of ccontaining LED lamp on this counterbore position and the cover.
The present invention is through to the improvement of circuit board and cover structure, makes that circuit board is unsettled to be located in the cavity that section bar is installed, and avoids directly contacting with section bar; Effectively prolonged the serviceable life of circuit board, and cover is provided with baffle plate, can prevents that foreign material such as sealing get into; Good water-proof effect; Protected circuit board, and overlay film and cover are onesize, more attractive in appearance in appearance.

Accompanying drawing 1 is the perspective view after the present invention assembling;
Accompanying drawing 2 is the decomposing state structural representation of accompanying drawing 1;
Accompanying drawing 3 is the A place structure for amplifying synoptic diagram of accompanying drawing 1.
Embodiment
For the ease of those skilled in the art's understanding, the present invention is done further description below in conjunction with accompanying drawing.
Like accompanying drawing 1,2, shown in 3, the present invention has disclosed a kind of LED display device, comprises section bar 1, cover 2, circuit board 3 and overlay film; Circuit board 3 is loaded on cover 2 back sides; Overlay film is mounted on cover 2 fronts, is pasted with the LED lamp on the circuit board 3, offers the groove position that the LED lamp is installed on the cover 2; Symmetrical dual-side is provided with clamp 4 is installed on the back side of said cover 2; Symmetrical two ends offer breach 5 on the circuit board 3, and cover 2 is installed on the section bar 1, and the circuit board 3 that is loaded on cover 2 back sides is suspended in the cavity of section bar 1.The back side of cover 2 is provided with the baffle plate 6 that is positioned at clamp 4 inboards, and foreign material such as effectively anti-sealing, oily thing get into the usability that has influence on circuit board, guarantee the serviceable life of circuit board.In addition, be pasted with overlay film on the front of cover, only offer counterbore position 7 on this overlay film, the shape and the quantity of groove position that is used for ccontaining LED lamp on this counterbore position 7 and the cover is consistent, and other positions of overlay film keep smooth, more attractive in appearance in appearance.
During installation, earlier circuit board and cover are fixed, in the groove position that the LED lamp inserting surface on the circuit board covers; Again cover is installed on the section bar and since the LED lamp between distance unequal, during design on circuit board 3 symmetry two ends offer breach; So not only reduce product weight but also practiced thrift cost of products; Be suspended on because of circuit board in the cavity of section bar, avoid contacting, guarantee the serviceable life and the performance of circuit board with the direct of shape.Through injecting glue cover and section bar are fixed, on the cover front, mount overlay film at last, make display device more succinct, attractive in appearance.
The foregoing description is a preferred implementation of the present invention, and in addition, the present invention also has other embodiments, and under the prerequisite that does not break away from inventive concept of the present invention, any conspicuous replacement is all within protection scope of the present invention.
